"Beer and chocolate are two pleasures that should be enjoyed and savored," said Samuel Adams founder Jim Koch. "We knew that we were up to the challenge to create an unexpected brew that could perfectly complement a Valentine's Day meal or be given as a special gift."

Brewing with chocolate essences is common in darker beers, such as stouts and porters.

The company described Samuel Adams Chocolate Bock as a dark beer with "a big, malty character with a complex full-body taster and velvety finish."

It added that the beer will sell for $14.99 per 750 milliliter bottle--roughly the size of a champagne bottle--and that it goes well with roasted chicken, chocolate mousse, chocolate cheesecake or fresh fruit.
